Why would you not want to look your best? You don't have to be high maintenance but taking care of some bushy brow is not a huge task. If you are going out in PJ bottoms and sweats you probably deserve the attention you get from some equally sloppy lazy guys.
I will usually limit where I am going to go based on how I am dressed. I know some people don't give a rip but it lacks class. I am not going to go into a nice place to eat in my shorts and tank I just got done working out in without a shower.
I hope you are on the Dean's list if you are too busy to take care of your hygiene
Guys like girls who can have fun, study AND take care of their looks. Taking care of your looks doesn't take much and it SHOULDN'T interfere with work, school or having fun. If it does, you're doing it wrong.
Expect to be overlooked
Me too but guys don't seem to mind...natural beauty is the best beauty :D
